Potential new strategy for relieving anxiety
Serotonin in the cerebellum alleviates anxiety-like behavior in mice, which counters the previously accepted role of serotonin in anxiety and may point to new treatment strategies.
2025-02-10
(Press-News.org) Understanding the neural circuits that drive anxiety may help researchers discover circuit-specific targets and therefore increase the precision of treatment strategies. Previous studies have separately suggested that increased serotonin levels and the cerebellum may play roles in anxiety. To explore the relationship between these ideas, Pei Chin, from the University of Pennsylvania, and George Augustine, from Temasek Life Sciences Laboratory, probed whether serotonin in the cerebellum causes anxiety behavior in mice. Contrary to previous findings, mice displaying anxiety-like behavior had lower amounts of cerebellar serotonin, while less anxious mice had increased serotonin in the cerebellum. Chin and Augustine then discovered that they could bidirectionally influence anxiety behavior by artificially stimulating or inhibiting the neurons that release serotonin into the cerebellum. According to the authors, this newfound role of cerebellar serotonin as a “brake” to alleviate anxiety is informative for work in more advanced animal models and the development of new treatment strategies.

Scientists develop corrosion-induced electrodes for biomass upgrading
2025-02-10
A research team led by Prof. ZHANG Jian from the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) has utilized metal corrosion to prepare high-performance electrodes, enabling efficient and cost-effective upgrading of bio-based 5-hydroxymethylfurfural (HMF). This study was published in Chem Catalysis.
Corrosion is a common phenomenon that can lead to material failure and economic losses. However, researchers are exploring its potential for beneficial applications, particularly in biomass upgrading.
Biomass is among the most abundant renewable resources on earth. Through catalytic conversion, ...
Contemporary hormonal contraception and risk of venous thromboembolism
2025-02-10
About The Study: This study showed venous thromboembolism (VTE) risk variation across hormonal contraceptives with highest rates for combined pills, especially those containing third-generation progestins, and no significant difference in risk for intrauterine devices (IUDs) relative to no use. For patches and implants, the increased VTE risk was uncertain due to limited data. Variation in VTE risk across products underscores the importance of personalized contraceptive counseling.

Victim-shooter relationships in mass shootings involving child victims
2025-02-10
About The Study: The findings of this study indicate that from 2009 through 2020, a child was most likely to be killed in a mass shooting by a parent or family member, rather than a stranger or a peer. While school shootings dominate media coverage, this study suggests that domestic violence plays a larger role in child mass shootings.

Health care company payouts favor shareholders, new research shows
2025-02-10
It’s widely recognized that health care is a growing expense for many Americans. However, what health care companies do with their profits — some made through government programs such as Medicare — remains murky.
To investigate this question, researchers at Yale School of Medicine (YSM) analyzed financial reports from 92 large U.S. health care companies. The results were published on Feb. 10 in a research letter in JAMA Internal Medicine.
The research team focused on U.S. health care companies on the Standard & Poor’s 500 (S&P 500), which follows the 500 largest companies traded on stock exchanges, to ...
Glucose-lowering medications and risk of COPD exacerbations in patients with type 2 diabetes
2025-02-10
About The Study: The results of this comparative effectiveness research study suggest that sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists (GLP-1RAs) were associated with a reduced risk of moderate or severe chronic obstructive pulmonary disease (COPD) exacerbations compared with dipeptidyl peptidase 4 inhibitors in adults with type 2 diabetes and active COPD. This may inform prescribing of glucose-lowering medications among patients with type 2 diabetes and active COPD.

Low to moderate prenatal alcohol exposure and facial shape of children at ages 6 to 8
2025-02-10
About The Study: Low to moderate prenatal alcohol exposure was associated with characteristic changes in the faces of children, which persisted until at least 6 to 8 years of age. A linear association between alcohol exposure levels and facial shape was not supported.

Earth’s inner core is less solid than previously thought
2025-02-10
The surface of the Earth’s inner core may be changing, as shown by a new study from USC scientists that detected structural changes near the planet’s center, published today in Nature Geoscience.
The changes of the inner core has long been a topic of debate for scientists. However, most research has been focused on assessing rotation. John Vidale, Dean’s Professor of Earth Sciences at the USC Dornsife College of Letters, Arts and Sciences and principal investigator of the study, said the researchers “didn’t set out to define the physical nature of the inner core.”
“What we ended up discovering is evidence that the near surface of Earth’s ...
Discovering the genetics of climate adaptation
2025-02-10
As climate change accelerates, plants face mounting pressure to adapt to shifting ecosystems and environmental conditions. This challenge is especially urgent for crops – plants resilient to drought and heat are essential to secure food supply in an unpredictable future. Fortunately, plants can adapt remarkably well to diverse environments and climates: Arabidopsis thaliana, for example, thrives in regions as climatically distinct as Sweden and Italy.
Understanding how plants naturally adapt to different ...
How does the brain differentiate new stimuli from old ones?
2025-02-10
The cerebral cortex is the largest part of a mammal’s brain, and by some measures the most important. In humans in particular, it’s where most things happen—like perception, thinking, memory storage and decision-making. One current hypothesis suggests that the cortex’s primary role is to predict what’s going to happen in the future by identifying and encoding new information it receives from the outside world and comparing it with what was expected to occur.
A new study published today in the ...
Eating gradually increasing doses of store-bought peanut butter enables children with high-threshold allergy to safely consume peanuts
2025-02-10
Children with high-threshold peanut allergy who ate gradually larger doses of store-bought peanut butter achieved significantly higher and long-lasting rates of desensitization compared to those who avoided peanuts, according to a new study led by researchers at the Icahn School of Medicine at Mount Sinai.
Results of the trial, sponsored and funded by the National Institutes of Health’s National Institute of Allergy and Infectious Diseases, appear in the Monday, February 10 issue of NEJM Evidence [https://doi.org/10.1056/EVIDoa2400306].
